Description
We present a general formalism for computing the matrix-elements squared for the emission of soft energy-ordered gluons to (theoretically) any order in perturbation theory at finite $N_c$. Our formalism is valid in the eikonal approximation. A Mathematica package is being developed for the automated calculation of all real/virtual eikonal squared-amplitudes necessary at a given order. For the purpose of illustration we show the explicit forms of the eikonal amplitudes up to the fifth order. In the large-$N_c$ limit our results coincide with those previously reported in literature.
